ALARM FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 722,587, dated March 10, 1903. Application led September 25,1902. Slerial No. 124,856. (No model.)

T0 all whom, it may concern.'

Be it known that I, JOSEPH M. JUSTEN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Alarm for Vehicles, of which the following is a specification.

The invention relates to improvements in alarms for vehicles. l Y

The object of the present invention is to provide forI fire apparatus, patrolwagons, streetcars, and other vehicles a simple and inexpensive alarm adapted to be operated by one of the wheels of a vehicle and capable of being readily thrown into and out of oper-v ation to enable the alarm to be sounded at the desired intervals.

The invention consists in the construction and novel combination and arrangementof parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of an alarm constructed in accordance with this invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a detail sectional view illustrating the manner of mounting the resilient pawl or dog and the ratchet-wheel.

Like numerals of reference designate corresponding parts in all the figures of the drawlngs.

l designates a wheel provided at its hub with an extension 2 and journaled on the spindle of an axle 3a in the usualmanner, and the said hub has secured to it by suitable means a friction-wheel 3, which is adapted to communicate motion to a friction-pinion 4 of a shaft 5. The shaft 5, which is disposed longitudinally of the axle, ,is located above the same andV is journaled in suitable bearings of a frame or bracket 6, which is secured to the axle by clips 7. The shaft 5 is capable ot'V a limited vertical movement to carry the friction-gears into and out of engagement, and the bracket or frame, which is provided with a rectangular body portion, has .a slot 8 at one end of the same to permit the said upward and downward movement of the shaft 5. The oth er end of the shaft 5 carries a gear 9, provided with spur-teeth and meshing with a pinion 10 of a counter-shaft 11, whiclris AY are provided with suitable pivots 16.

l 'rapidly rotated by the said gearing when the yfriction pinion is in engagement with the friction-wheel 3. The counter-shaft l1 is jou rnaled in suitable bearings of the ends of the rectangular portion of the bracket or frame, which is provided with a rectangularguard 12, having bearings for the reception of the shafts and extending around the spur-gears. The guard is rectangular and is formed integral with the adjacent end of theA bracket or frame.

The shaft 11 is extended outward beyond lthe frame and is provided at its outer end .with a rotary bell-engaging device consisting lof a support and a pair of pivoted clappers or. hammers 13, arranged to engage a gong let.

The support'consists of a pair of bars 15, centrally secured to the shaft and spaced apart to receive the clappers or hammers 13, which The gong is mounted on a post or stem 17 secured to an arm 18, which extends rearward or outward from the axle; but it may be located in advance of.the same, if' desired. The arm 1S, which is disposed horizontally, is preferably formed integral with a bar or extension 19 of the bracket or frame. As the shaft 11 4isrotated the bell hammers or clappers are thrown outward and are caused to strike the gong at the outer edge thereof, whereby a continuous alarm is sounded while the friction-pinion 4 is in engagement with the gearwheel 3.

The friction-pinion is normally held out of contact with the friction gear-wheel by means of a coiled spring 20, disposed on a rod or bar '21, which is pivoted atits upper end to one arm of a lever y.22, and the latter is fulcrumed between its ends on an arm or post 23 of the frame or bracket. The frame or bracket is provided at its top with the said arm 23, and the spring is interposed between the frame and the lever. The lower end of the bar 21 is provided with a sleeve or bearing 24 to receive the shaft 5, and the outer end of the lever is connected with a cord 25 or other suitable means for 'enabling the lever to be readily oscillated for carrying the friction-pinion into engagement with the friction-Wheel.

In order to enable the gong to be sounded when a vehicle is not in motion, the lever 22 is provided With a resilient pawl 26, depending from the arm to which the operatingcord 25 is connected and provided at its lower end with a tooth 27, arranged to engage and rotate a ratchet-Wheel 28 When the lever 22 is lifted by the cord 25. The upper portion of the pawl is bent at an angle to clear the frame or bracket, and the ratchet-Wheel is mounted on the shaft 5, which is carried by the said lever. By oscillating the lever 22 the gong may be sounded when a vehicle is not in motion.

It Will be seen that the alarm is exceedingly simple and inexpensive in construction, that it is positive and reliable in operation, and that it is adapted for iire apparatus, policepatrol wagons, cars, and various other forms of vehicles. It Will also be apparent that the alarm is readily operated to carry the friction-gears into engagement with each other and that when in engagement a continuous alarm will be sounded and that when the operating mechanism is released the spring 2O will automatically carry the frictionpinion 4 out of engagement with the friction-pinion 3.

What I claim isl. An apparatus of the class described comprising a b racket or frame designed to be mounted on a vehicle, a transverse shaft mounted in the bracket or frame and capable of a limited oscillatory movement, gearing connecting the transverse shaft with one of the Wheels and adapted to be separated by the oscillatory movement of the said shaft, a countershaft mounted in the frame or bracket, gearing connecting the said shafts, means carried by the counter-shaft for striking a gong, and spring-actuated operating mechanism connected with the transverse shaft and normally holding the same out of operation, substantially as described.

2. An apparatus of the class described comprising an upright frame or bracket designed to be mounted on a vehicle, a transverse shaft mounted in the frame or bracket and capable of a limited upward and downward movement, a counter-shaft also mounted in the frame or bracket and provided with means for striking a gong, gears connecting the shafts, a lever fulcrumed ou the frame or bracket, a rod connected with the lever and provided with a bearing-sleeve receiving the transverse shaft, a spring for holding the transverse shaft normally in an elevated position, gearing for connecting the transverse shaft with a wheel of the vehicle, said gearing being separable by the upward and downward movement of the transverse shaft, and means for operating the lever, substantially as described.

3. An apparatus of the class described comprising a frame or bracket designed to be mounted on a vehicle, a shaft mounted in the frame or bracket and capable of alimited oscillation, gearing for communicating the motion of the vehicle to the shaft, said gearing being separable by the oscillatory movement of the said shaft, a spring-actuated rod or bar having a sleeve receiving the shaft, a lever connected with the spring-actuated rod or bar, a shaft provided with means for striking a gong,and gearing connecting the shafts,sub stautially as described.
